The adjustable minimum difference between switch-on temperature and switch-off temperture (hysteresis) avoids that the controller switches on and off again at too low temperature differences. When flowmeter is used and when the the filter pump is switched on, this option monitors whether there is a flow rate in the solar circuit. If the controller does not receive any pulse after 2 minutes, the filter pump will be switchedoff and an error message will be generated. This option is used for switching on an extra runtime of the filter pump (in h) if necessary (e.g. in the case of polluted pool water). As soon as a contact is detected at the Din input, the filter pump starts and remains switched-on for the adjusted period of time (extra runtime).The filter minimum runtime will not be influenced by this function. The external release function is used for releasing the pump for solar loading (e.g. for preventing the controller from switching on the pump during pump maintenance.)
